Earlier I used to activate Bangla (Unijoy) layout from ibus preference. Accessed ibus Keyboard Input Methods, ibus preference would only show up a handful of chinese scripts. I had to install "ibus-m17n" to get the whole package which included the unijoy layout.
However, starting 13.10, I can't find the ibus preference/Keyboard Input Method screen at all. It's been replaced by text entry field, where there are Bengali layouts but not Unijoy. Terminal shows that ibus is installed but I can't bring up the front-end. I even installed ibus-m17n but still the unijoy layout doesn't show up.
I know it wouldn't matter for a lot of people here since it's just a local language, but I need it. I'm a journalist and run a few bilingual websites where I need to write a lot -- that includes Bangla and English. I must write Bangla using the layout that I -- and a lot of people over here -- am familiar with most.
